The Next Generation GONG (ngGONG) Project: Ground-based Synoptic Studies of the Sun
Abstract
Ground-based synoptic solar observations provide crucial contextual data used to model the large-scale state of the heliosphere. Existing ground-based synoptic programs are aging rapidly and are used in ways that differ from their original objectives. Most prominently, GONG was designed for helioseismology but is most demanded today as a provider of the magnetic boundary conditions for solar wind models. A wealth of theoretical knowledge about the connectivity between the Sun and the planets has emerged in recent years. NSO and HAO (and other international partners) are collaborating in defining a next-generation GONG (ngGONG) network that incorporates this knowledge. This contribution describes current and future contextual synoptic observations needed to fully exploit our new understanding of the underlying microphysics that leads to magnetic linkages between the Earth and the Sun. This combination of a better understanding of small-scale processes and the appropriate global context will enable a physics-based approach to Space Weather comparable to Terrestrial Weather forecasting.
